Abstract:Proton magnetic resonance spectroscopic imaging (1H‐MRSI) is a powerful tool that enables the multidimensional non‐invasive mapping of the neurochemical profile at high resolution over the entire brain. The constant demand for higher spatial resolution in 1H‐MRSI has led to increased interest in post‐processing‐based denoising methods aimed at reducing noise variance. The aim of the present study was to implement two noise‐reduction techniques, Marchenko–Pastur principal component analysis (MP‐PCA) based denoi… Show more
